The invention relates to an improvement in the assembly structure of a high door. This improvement is characterized by the inner side of an upper longer region (above the handle) of the left edge-sealing angle bar and the inner side of a lower shorter region (below the handle) of the left edge-sealing angle bar being inlaid with two U-shaped reinforcing irons the length of which corresponds to the length of the two regions. A first wood strip the length of which is slightly shorter than that of the left edge-sealing angle bar is inserted into the U--shape of the two U-shaped reinforcing irons, then joined, by a nail gun and an adhesive, to a second wood strip. The handle position is then inlaid with a reinforcing angle bar. The inner side of the right edge-sealing angle bar is inlaid with a U-shaped reinforcing iron the length of which is slightly shorter than that of the right edge-sealing angle bar. A third wood strip with a length corresponding to that of the U-shaped reinforcing iron is inserted therein and joined, by a nail gun and adhesive, to a fourth wood strip. The structure is coated with an adhesive and press-assembled with two contoured door skins. After assembly, a hole is drilled in the bottom edge-sealing angle bar and the hollow core formed by the two contoured door skins is filled up with ammonium polyester foamed plastic to form a high door structure which will not bend or deform.
